“You have no idea who you're dealing with,”
—Umber, in Flashback
Umber was a Shade who kept her appearance concealed with the Neverseen cloak. She was described to be a more powerful Shade than Tam Song. She was one of Wylie Endal's abductors. Her voice was said to be soft and raspy, like curls of smoke. Keefe stated that Trix and Umber commonly worked together.
Her nails were said to be covered in thick, sludgy darkness that seemed to pour out of her and curl into long claws.
Umber knew how to use Shadowflux, the sixth element. In Flashback, she was killed by being crushed by the door leading into the Everglen troll hive. Her skull was so crushed that her real identity is still unknown.
